Extrusion

Biax Laboratories, LLC now has lab sheet extrusion capabilities, enhancing our current biaxial orientation capabilities. In March of 2013, Biax Labs installed a ZSK-25 Krupp Werner & Pfleiderer 25mm twin screw, co-rotating extruder. This extruder feeds a casting/calendering vertical 3 roll stack. Material can be wound after extrusion, or fed straight to the Biax MDO line.

  • 25mm co-rotating screws.
  • 40:1 L/D.
  • AC motor and vector drive 10:1 constant torque over base speed range.

  • Electric barrel heaters and a cooling manifold for heating and cooling in a controlled manner.
  • 9 barrel sections and 10 heating zones.
  • Liquid injection capabilities.
  • Temperature controlled vertical 3-roll stack.

Calendering/Casting Unit:

  • Clutch driven, variable speed wind-up unit, utilized if only extrusion is required.
  • 3-roll vertical stack.
  • 12″ roll diameter.
  • Variable speed drive.
  • Calendering capability.

In addition to mixing screws Biax Laboratories, LLC #3 – 14 inch and #1 – 16 inch chrome plated P-20 Cloeren sheet dies are available for customer use.
